Paper format. National Exams, December 2017. Three (3) hours. OPEN BOOK; an approved Casio or Sharp calculator is permitted. Question 1 is compulsory and carries 40 marks; four (4) of the remaining six (6) questions are chosen, each worth 15 marks, for 100 marks attempted out of 130 printed. Only the first five questions appearing in the answer book are marked. The marking scheme is printed on page 4 of the paper and is reproduced against each question below. Most answers are expected in essay form, supported by tables, figures and charts.
How to use this document. Every one of the seven printed questions is answered in full, not just the five a candidate would attempt, so that the set works as a study resource. This is a descriptive design-methodology paper: the marks are for method, structure and judgement rather than for arithmetic. Where a number genuinely sharpens an argument — a DFA index, a process break-even, a capability index, a material index — it is computed explicitly and framed with Given. and Find. so the reasoning can be checked. All monetary figures are Canadian dollars.
